Description

[0001] TERMINAL AND OPERATING METHOD THEREOF [0002]

The present invention relates to a terminal and a method of operation thereof, and more particularly to a method of controlling a location information module, such as a global positioning system (GPS) module.

A terminal can be divided into a mobile terminal (mobile / portable terminal) and a stationary terminal according to whether the terminal can be moved. The mobile terminal can be divided into a handheld terminal and a vehicle mount terminal according to whether the user can directly carry the mobile terminal.

Such a terminal has various functions, for example, in the form of a multimedia device having multiple functions such as photographing and photographing of a moving picture, reproduction of a music or video file, reception of a game and broadcasting, etc. .

In particular, the terminal provides a navigation function, a peripheral facility recommendation function, and a media tagging function based on location information provided by a location information module such as a GPS module. The navigation function provides a user's location or directions using a map. The recommendation for nearby facilities is a function for recommending a place such as a restaurant near the user's current location. The media tagging function is applied to a recorded image or video. Inserts the location information of the shooting location.

However, the location information module takes a certain time to receive the satellite signal to obtain the location information. This constant time is called the time to first fix (TTFF). In particular, since the location information module takes a relatively long time from 30 seconds to 1 minute to initially receive a satellite signal and obtain location information without the available satellite information, the location information module uses various functions based on the location information described above. Inconvenience to use is caused.

Accordingly, various techniques for shortening the initial position acquisition time of the location information module have been developed. According to one example, the location information module periodically receives a GPS signal even without performing location information acquisition in a sleep mode of the terminal to maintain available satellite information such as GPS system time. Thereafter, when the location information module transitions to the location information acquisition state, the location information module may perform fast location information acquisition within a few seconds. However, since the location information module periodically receives the GPS signal in the sleep mode that needs to maintain the minimum power consumption, battery life is shortened.

An embodiment of the present invention provides a terminal capable of quickly obtaining location information while minimizing battery life.

A method of operating a mobile terminal according to an embodiment of the present invention comprises the steps of: receiving a user input for determining a start condition of a satellite information maintenance mode of a location information module; Determining a start condition of the satellite information maintenance mode based on the user input; And if the start condition of the satellite information maintenance mode is satisfied, sending a satellite information maintenance command to the location information module, wherein the mobile terminal sends the satellite information maintenance command to the location information module from the location information module. Do not receive location information.

The terminal according to various embodiments of the present disclosure may perform fast location information acquisition while minimizing battery life.

Next, an operation of the location information module 115 according to an embodiment of the present invention will be described with reference to FIGS. 2 to 3.

2 is a state transition diagram illustrating an operation of a location information module according to an embodiment of the present invention.

As shown in FIG. 2, the location information module 115 includes a slow location acquisition mode M101, a location measurement mode M103, a satellite information non-holding mode M105, a satellite information maintenance mode M107, and a fast location acquisition. It operates in the mode M109.

When the location information module 115 is turned on to supply power to the location information module 115, the location information module 115 transitions the operation mode to the slow location acquisition mode M101 (S101). In the slow position acquisition mode M101, the position information module 115 attempts to acquire a position without available satellite information such as satellite system time information. As such, obtaining location coordinate information without the available satellite information by the location information module 115 may be referred to as a cold start. In the case of a cold start, the location information module 115 has a TTFF of approximately 30 seconds to one minute.

When the position information module 115 completes the position measurement in the slow position acquisition mode M101, the position information module 115 transitions the operation mode from the slow position acquisition mode M101 to the position measurement mode M103 (S103). ). In the position measurement mode M103, the position information module 115 may output position coordinate information at a period equal to 1 second while maintaining the position measurement.

When the location information module 115 receives the location measurement end command and the satellite information non-maintenance command from the controller 180, the location information module 115 transitions the operation mode to the satellite information non-maintenance mode M105 (S105). . The satellite information module 115 may receive a satellite information non-maintenance command before receiving the position measurement end command, or may receive a satellite information non-maintenance command together with the position measurement end command. The satellite information non-holding mode M105 may be a sleep mode of the location information module 115. In the satellite information non-maintenance mode M105, the location information module 115 does not take a position measurement and neither receives a satellite signal nor maintains available satellite information.

When the location information module 115 receives the location measurement end command and the satellite information retention command from the controller 180, the location information module 115 transitions the operation mode to the satellite information maintenance mode M107 (S107). The satellite information maintenance command may be a command such that the location information module 115 receives satellite signals to retain available satellite information but does not perform position measurement using the received satellite signals. The satellite information module 115 may receive the satellite information maintenance command before receiving the location measurement end command, or may receive the satellite information maintenance command together with the location measurement end command. In the satellite information maintenance mode M107, the location information module 115 receives satellite signals and retains available satellite information without making location measurements. In the satellite information maintenance mode M107, the satellite information module 115 may receive the satellite signal periodically or aperiodically or according to a period determined by a specific rule. The location information module 115 receives satellite signals and retains available satellite information, but does not perform location measurement using the received satellite signals. Therefore, the location information module 115 does not provide location information to the mobile terminal 100. 100 does not receive the location information from the location information module 115 while sending a satellite information maintenance command to the location information module 115.

Meanwhile, the location information module 115 may have a flag related to satellite information maintenance, and the satellite information maintenance command and the satellite information non-maintenance command may be setting commands of flags related to satellite information maintenance. If the flag related to the maintenance of the satellite information is set to a value corresponding to the maintenance of the satellite information by the satellite information maintenance command, the location information module 115 may operate in the satellite information maintenance mode M107. If the flag related to the maintenance of the satellite information is set to a value corresponding to the satellite information non-maintenance by the satellite information non-maintenance command, the location information module 115 may operate in the satellite information non-maintenance mode M105. For example, the value corresponding to maintaining satellite information may be 1, and the value corresponding to non-satellite information may be 0.

In one embodiment, the satellite information maintenance mode M107 may include a first sub-mode M107a and a second sub-mode M107b which are alternately changed periodically. The first sub mode M107a may be a satellite information collection mode. The second sub mode M107b may be a sleep mode of the location information module 115.

On the other hand, when the location information module 115 receives the satellite information maintenance command from the controller 180 in the satellite information non-maintenance mode M105, the location information module 115 transitions the operation mode to the satellite information maintenance mode M107. (S109). In addition, when the location information module 115 receives the satellite information non-holding command from the controller 180 in the satellite information holding mode M107, the location information module 115 switches the operation mode to the satellite information non-holding mode M105. Transition (S111).

When the location information module 115 receives a location measurement start command from the controller 180 in the satellite information non-maintenance mode M105, the location information module 115 confirms whether the satellite information holds available satellite information. If no satellite information is available, the location information module 115 transitions the operation mode to the slow location acquisition mode M101 (S113). Even if the current operation mode is the satellite information non-maintenance mode M105, the location information module 115 may retain the available satellite information if a long time has not passed since entering the satellite information non-maintenance mode M105. . If the location information module 115 holds available satellite information in the satellite information non-maintenance mode M105, the location information module 115 may transition the operation mode to the fast location acquisition mode M109.

When the position information module 115 receives the position measurement start command from the controller 180 in the satellite information maintenance mode M107, the position information module 115 checks whether the satellite module holds available satellite information. If the location information module 115 has available satellite information, the location information module 115 transitions the operation mode to the fast location acquisition mode M109 (S115). Even if the current operation mode is the satellite information maintenance mode M107, the reception state of the satellite signal may not be good and the location information module 115 may not have available satellite information. If the location information module 115 does not hold available satellite information in the satellite information maintenance mode M107, the location information module 115 may transition the operation mode to the slow location acquisition mode M101.

In the fast location acquisition mode M109, the location information module 115 attempts location acquisition based on available satellite information, such as satellite system time information. As such, obtaining location coordinate information based on available satellite information by the location information module 115 may be referred to as a hot start. In the case of hot start, the location information module 115 has a TTFF of approximately 5 seconds or less.

3 shows power consumption over time in the satellite information maintenance mode according to an embodiment of the present invention.

As shown in FIG. 3, in the satellite information maintenance mode M107, the location information module 115 may include a first sub mode M107a corresponding to the satellite information collection mode and a second sub mode M107b corresponding to the sleep mode. Alternates between modes of operation. As shown in FIG. 3, the satellite information module 115 may periodically change an operation mode between the first sub mode M107a and the second sub mode M107b. As shown in FIG. 3, power consumption in the first sub mode M107a is greater than power consumption in the second sub mode M107b.

In the slow position acquisition mode M101, the position measurement mode M103, the satellite information acquisition mode of the satellite information maintenance mode M107, and the quick position acquisition mode M109, the location information module 115 receives and analyzes satellite signals. It consumes relatively large power.

In the dormant mode of the satellite information non-maintenance mode M105 and the satellite information maintenance mode M107, the location information module 115 does not receive satellite signals and thus consumes relatively small power.

Next, a network topology according to an embodiment of the present invention will be described with reference to FIG. 4.

4 shows a network topology according to an embodiment of the invention.

As shown in FIG. 4, a network topology according to an embodiment of the present invention includes a mobile terminal 100, a network 10, and a synchronization server 200.

The mobile terminal 100 wirelessly connects to the network 10 through at least one of the modules in the wireless communication unit 110. In another embodiment, the mobile terminal 100 may be connected to the network 10 by wire.

The synchronization server 200, such as a cloud server, connects to the network 10 by wire or wirelessly.
